YES They put in my air conditioner last year. They are wonderful to work with. Did a great job and treated me beautifully. I recommend the highly. In fact I could not remember for sure the company name so I called them and asked them to look up and see if I was their customer last year. Yes I was. And I would call them for all things. They do A.C and heating. They do repairs and maintenance for heat and a/c. Yes you will love them. They are honest and won't charge you unfairly in any way. They guys are good people and I considered them my family. I am going to be sure I have their company name in my records so I can recommend them anytime.
